Example Embodiment

[0021] Example 1:

[0022] Weigh 25.2 grams of PV23, 0.63 grams of PBK7, and 1000 grams of CSC-B base material. Mix the above materials evenly, and then apply the obtained composition on the substrate evenly and evenly by mechanical coating under the conditions of relative humidity of 50%±5% and room temperature of 23±2°C. It is metallic or non-metallic material. The wet film thickness of the coating is 250m, and then placed in a 50±2°C precision oven to dry for 3-4h to constant weight, take it out, cool to room temperature, and obtain the color characterization.

Abstract

The invention discloses a composition expressing the 2.5P 5/9 pigment, and a technical method for preparing a color token by using the composition. The composition consists of the following ingredients according to parts by weight: 995 parts to 1005 parts of CSC-B base, 24.6 parts to 25.8 parts of PV23, the pigment content of which is 30 percent; and 0.58 part to 0.69 part of PBK7, the pigment content of which is 9 percent. The major ingredient of the CSC-B base is acrylic copolymer with the content of 30 percent to 40 percent. TiO2 is selected as a major white pigment, taking up the content of 8 percent to 12 percent. The contrast ratio of the base is 0.78 to 0.82, the Stormer viscosity thereof is 90KU to 100KU and the glossiness thereof is 5 to 10 when the incidence angle is 85 degrees. The color token of the invention has good weatherability, stability and proportioning reproducibility, and the used raw materials and the process comply with the environment protection requirements and the standards of low VOC and zero VOC; compared with the standard values in the national standard theoretical model of the Chinese Color System, the color token has small difference in color and high accurate degree of color realization, therefore, the color token can be widely applied to a plurality of color-related fields.

Description

【Technical field】 [0001] The present invention relates to a composition, in particular to a composition of pigments, and a technical method for preparing color representations from the composition. 【Background technique】 [0002] A color includes hue, lightness and chroma. As long as the hue, lightness and chroma are determined, a unique color can be determined. The Chinese color system GB / T 15608-1995 stipulates that in the theoretical model of the Chinese color system, any color can be calibrated by the hue, lightness and chroma on the color plane, and given a certain label. The calibration method is to first write the hue H, then write the lightness V, write the chroma C after the slash, expressed as H V / C, take the color 10BG 5.5 / 6 as an example, 10BG means the hue, 5.5 means the lightness, and 6 means the color Spend. [0003] From the theoretical value in the theoretical model to the production process of the color representation, many important links such as color d...
